A shaft is turning at 73.8 rad/s at time zero. Thereafter, its angular acceleration is given by
a = -10.1 rad/s2 - 4.44 t rad/s3.
where t is the elapsed time. Calculate its angular speed at t = 2.58 s
1/2(Angular accel formula)+ 73.8t+0= theta final
The Attempt at a Solution
do i take the integral of the accel formula then the velocity the plug in 2.58?
